Application lled August 29, 1916. :Sei-'inl No. 117,434.l

To all whom it may concern: l

Be it known that I, CARL H. Bissau., a citizen of the United States anda resident new and useful Electric Service-Box, of which the followingis a specification.

In describing this invention reference is had `tothe accompanyingdrawings in which like characters designate parts in all the views. v

Figure l is a plan view,

away, of one form of my invention.

, Fig. 2 is an elevation of partsseen in corresponding` Fi i. y lFig. 3is a vertical lo itudinal sectional view taken nearly central y of Fig.Ajl. Figs. 4 and 5 are fragmentary views illusthe position of the andthe door when the'switch member is open and the door is closed, and whenthe door is open from its position shown in Fig. 3.

This invention comprises generally, a box having a movableV switchmember therein, vand means vfor preventing access to the. interior ofthe box except when the switch member is open. Preferably the operatingmeans for the Kmovable switch member is the cover of the box, and acousaid means and the switch member and is detachablyconnected to one oftheparts it connects when the switch member is in open position, andautomaticall disconnects upon opening movement oft ecover. .l

More specifically, 4this `invention comprises, a boxhaving `twocompartments arcarried by ranged side by side or end to end, one com--partment having amovable door, a switch `located in the othercompartment and inor` terminals :in d a cluding switch contactsterminals located county oi Onondaga and ,State of New York, haveinvented a certain he invention consists in the combination andconstructions hereinafter set forth vand claimed.

partly broken connected to the switch terminals and coactmg meansassociated with the movable switch member and lthe door to preventopening of the door when the switch is closed and closing ofthe switchwhen-the door is open, so that at no time, is it possible to open thebox Awithout breaking the circuit This invention relates to acombination through .the electricalV appliances therein. The box is openat one side as its top and is closed by a removable cover which supportsthe door and also the means for operatingl the vmovable member of theswitch, said means having a detachable connection with the switchmember. l

1 designates the box as awhole which is lhere shownas oblong in generalform and as having means at one end as an internally threaded nipple 2for connection with an electric conduit. 3 is the cover for the openside or top oit the box, the cover being se cured in position by anysuitable means as cap screws 4: and having a flange 5 extending alonlone edgel thereof toward the bottoni of, the ox, the iange fitting acomplemental Ycut out in the contiguous side of the box. v

The' nipple 2 is preferably carried by, and

formed integral with a plate 'which is sel cured to the end of the boxin any suitable manner as by cap screws 7. This plate 6 lisinterchangeable with a closed endplate as 8. 9 is the compartmentlocated in one end of the box and extending to -near the middle thereof.10 designates the other compart- ,ment in which electric Vappliances asvfuses are located, the compartment 10 being. located in the oppositeend ot the box. l

12 designates the door for the `fuse 'compartment, the door being partof the cover A3 and being hinged or mounted on a shaft oif .axis 13extending transversely of thel cover andthe box near the middle thereof.LThe;

door has a latch 14 at its free end, as a reciprocally movable bolthaving a handle liby' means of which it is moved in one direction voutot' operative position against a spring 16, the` bolt Icoacting with aperforated lug 1 on The cover 3 curves upwardly as at 1 8 over.

the switch compartment to provide space for thevmovement of the switchmember. The

top is provided with a suitable lug 19 over which the ring 20 on thedoor 12 may be Y hooked in order to hold the door 12 open.

21 is :in insulating base located within the box and extending into bothcompartments.

22 and 23 are switch contacts and terminals located in the compartment 9and mount( d on the block 21.

21 and are terminals-located in the fuse compartment on the base 2l, theterminals 2a being electrically connected to the switch terminals 23.rhe terminals 25 and the switch contacts 22 are provided with suitablebinding devices 26, 2T for connection to the service wires.

28 is the movable switch member which carries 'the blades or knives 29which are pivoted or hinged at 30 to the contacts 23, this member 28also including a cross head or bar to which is detachably connected themeans for operating the switch member. Said means usually includes arock arm 31 mounted upon a rock shaft 32 supported by and extendingthrough the flange 5 of the cover 3 .in line with the pivot 3() andhaving a handle 33 at its outer end.

' T he rock arm 81 is detachably connected -to the cross bar ot' theswitch -member 28 b v an arm 34 extending laterally from the free end ofthe a `m 31 and along the cross bar and having a coupling formed with alU-shaped channel 35 at its free end which receives the (ross bar andhence couples the arm 3i to the cross bar, the. channel facing towardthe axis of the switch member so that the arm or the coupling thereofcannot be lii'ted a Yay from the switch bar except when the switchisopen (Fig. 4) The cross bar vis formed with a groove 36 for receivingthe sides of the channel. The cover 3 can only be detached from the boxwhen the switch member is in open position as the coupling or theU-shaped channel thereof, cannot be detached from the cross bar ot theswitch member 28, when theswitch is in any other position. Hence, amovement to displace the cover 3 when the switch member is in closedposition will cause the switch member 28 to open. The cover 3 can bereplaced only when the switch member is in open position and .for thepurpose ot guiding the cross bar of the switch member 28 into theU-shaped channel 35 of the coupA ling. the coupling is provided with aninclined extension or guide 37 on one side of the channel.

The axis S2 of the switch member and the axis 13 of the door are locatedtransversely of the box near the middle thereof. and near and parallelto each other, and coacting means are provided on the operating meansi'or the movable switch member and the' door 12 which means control theopening and closing of said switch member and the door. As here shown.rock arms 38, 39 are `associated respectively with the door 12 and thearm 31 of the switch operating means.v t'herroclr arm 23S on the door 12extending into the Ypath of the rock arm 39 associated with the switchmember to prevent closing of the switch member when the door is o penand the switch member is open, and the arm on the switch member beingarranged in position to prevent opening of the door 12 when the switchmember is closed as seen in Fig. 3. Thus the switch member must beopened into its position shown in Fig. -l before the door can be openedintothe position seen in l? and when the parts are in the position shownin` Fig; 5, the switch member cannot be closed as the rock arm 38 ou thedoor is arranged in the path oi movementof the rock arm 39.

The sv. it-h arm 31 is concaved to permit' the movement ot the arm 39 onthe door' 12.

This box is particularly advantageous in that both compartments are inthe same plane so that the electrical appliances can be mounted on aycommon base and it is fun ther advantageous in that it provides aparticularly simple and elicient means for making the device safeagainst careless attendants.
